Dirty Ho (爛頭何 Lan tou He) is a 1979 Hong Kong martial arts comedy film directed by Lau Kar-leung and starring Gordon Liu and Wong Yue.

Ho Ching, who is not too bright, can't figure out why his efforts to fight with the seemingly cowardly, effete Wang inevitably result in clumsy disaster.

Ho Ching is let go by the police and attempts to get "his" jewelry back from Wang, which again ends in clumsy disaster for him and eventually to a fight with some local thugs who are looking for him (who they claimed stole from them).

Ho is initially puzzled at this since he has not detected any kung fu prowess in his master at all, yet goes along with it since Wang has the poison antidote, which must be administered in small doses over time.

Initially, he remains a clueless bystander during two attempts on Wang's life: first, an attack at a wine-tasting, and then a visit to an antique-dealer's shop, both sponsored by General Liang at the orders of the 4th Prince (who wants his brother dead).

Only at the end of the antique-shop attack does Ho figure out what's going on and intervene, but Wang receives a wound in the leg through a stratagem of the antiques dealer.

Lau Kar-leung noted Hui's abilities in an audition tape for Chang Cheh's The Brave Archer and hired her to take over.
